Answer :
Final answer:
IQ is standardized with an average of 100, providing a point of comparison across individuals or groups. The Flynn effect observes a rise in IQ scores across generations, however, the exact rate is not specified as 15 or 5 points every 3 years.
Explanation:
Based on the presented options, the true statements about IQ are: a) IQ is standardized with an average of 100, meaning your IQ score is relative to the scores of others. The Flynn effect describes a generally observed trend that each generation has a significantly higher IQ than the previous generation. However, the rate of increase is not specified as 15 or 5 points every 3 years in the available literature.
IQ tests are designed to provide scores that follow what's called a 'bell curve', which means most people score around the average (100), and scores decrease in frequency the farther they are from the average. The concept of IQ standardization is important as it allows the comparison of scores across different individuals or groups. It doesn't mean that it's solely based on your performance, but it's more about your performance relative to others.
The so-called Flynn effect named after James Flynn, describes the observed rise in IQ scores over time, suggesting improvements in overall cognitive abilities across generations. However, the exact increase (either 15 or 5 points every 3 years) is a point of ongoing debate and research, and thus, hasn't been clearly defined.
